Morphologic changes in intestinal mucosa with urinary contact--effects of urine or disuse?

Abstract

Mucosa in contact with urine seems to maintain surface characteristics better than mucosa deprived of luminal stimulation, indicating that factors present in the urine may be important for the epithelial cell physiology. Certain intracellular changes were found more often in mucosa exposed to urine, but there were no major differences. The changes noticed may indicate enterocyte adaptation to a new physiologic environment.
